Product Overview
The Hitch Pin – Plain Shank is a medium-carbon steel coupling pin supplied without any pre-fitted retention device. The plain shank allows the operator to fit their own preferred retention method, whether a linch pin, standard hair pin, R-clip, or locking collar, to suit the specific application requirements and the retention standard that applies to the equipment or jurisdiction.
Plain shank pins are the most flexible variant in the hitch pin range because they place the choice of retention device entirely with the operator. This is the appropriate choice when the required retention type differs from the pre-assembled options, when the operator prefers to standardise on a single retention clip type across multiple pin sizes, or when the pin is being supplied as a spare body without a replacement clip.
Material Specification and Technical Detail
The plain shank is produced from medium-carbon steel bar, machined to the specified diameter, overall length, and cross-hole position. Zinc plating is applied after machining. The cross-hole is sized to accept the standard range of retention devices used across agricultural coupling applications, including wire hair pins, R-clips, and linch pins of the appropriate diameter.
The plain shank variant uses identical shank geometry to the pre-assembled H-type and chain retention variants. This means a plain shank pin can be fitted in any application where an L-HPH or chain pin of the same diameter is currently used, with the operator’s own retention device providing the clip function.

Application and Operating Environment
The Plain Shank hitch pin is used in all standard coupling and linkage pin applications. It is particularly suited to operations where the operator maintains a stock of specific retention clips separately and fits them to pins as required, rather than relying on pre-assembled units. Compatible with John Deere, Massey Ferguson, New Holland, Kubota, Case IH, Fendt, and Claas across the standard coupling pin diameter range.
A common use pattern is to supply plain shank pins as replacement bodies when the original pin has worn but the hair pin is still serviceable, allowing the retention device to be reused without purchasing a complete pre-assembled unit. The plain shank also allows the operator to upgrade the retention device independently, for example by fitting a locking collar in place of a hair pin where regulations require it.
OEM Compatibility and Cross-Reference
The Plain Shank hitch pin is dimensionally compatible with coupling pin specifications from John Deere, Massey Ferguson, New Holland, Kubota, Case IH, Fendt, and Claas. Shank diameter, overall length, and cross-hole position match the equivalent pre-assembled variants.
Distributors can stock plain shank pins alongside pre-assembled variants to give customers the choice of retention method without needing to hold separate stock for every pin size and retention type combination. Our 3-point hitch kit consolidates the most frequently replaced linkage components into a single order.
Installation Procedure
Follow the steps below for correct installation of the Hitch Pin – Plain Shank in standard agricultural coupling applications.
01
Select the Correct Diameter and Length
Match the shank OA to the coupling hole and confirm the overall length is correct for the coupling jaw width. Measure the existing pin if in doubt.
02
Insert the Pin
Push the plain shank through the coupling hole until the head seats against the coupling face. The cross-hole should be clear on the exit side for retention device fitting.
03
Fit Your Retention Device
Insert the hair pin, R-clip, linch pin, or locking collar of the correct diameter through the cross-hole. Ensure it is fully engaged before applying any coupling load.
04
Match Retention to Application
For road transport or heavy trailer applications, use a positive-lock device rather than a standard hair pin. For standard field linkage use, a hair pin or R-clip of the correct wire diameter is appropriate.

Customer Feedback
“We have been stocking the Hitch Pin – Plain Shank for two seasons across our dealer network in Normandy. Fit to John Deere and Claas equipment has been exact and we have had zero returns on dimensional grounds. The zinc finish is holding up well through wet field conditions.”
Patrick F. – France
“The Hitch Pin – Plain Shank is exactly what we needed for our contracting fleet. Fast implement changes are important when you are working to a tight harvest schedule, and having a pin that couples and uncouples reliably with one hand saves time on every field entry.”
Gareth W. – United Kingdom
“Good product and straightforward ordering process. The Hitch Pin – Plain Shank covers all the pin sizes we need for our Fendt and New Holland machines. Packaging is solid and part numbers are clearly marked, which makes goods-in processing quick.”
Lars N. – Denmark
